Only according to cultural marxist anthropologists who have a vested interest in denying the biological reality of race. There was a study done on medical students in some african country, whose name I don't remember, and they scored around the expected 80 point range. Why is that? They can't blame it on oppression or anything other factors. Chinese peasants still score around 100, despite having no education. So your argument doesn't seem to work. As for arabs, they aren't really a race. Egyptians, syrians etc, are all arabised, not arabs as such. It wasn't the arabian tribemen from the arabian peninsula who made all the advancements; they themselves went back to their simple lives not long after the openings of the middle east. The islamic intellectual tradtion, specifically ashari theology, is essentially Persian, the whole line of philosophical argumentation that came via the mutazila into asharism came by the persian and christian converts to islam. Even in grammar, the one to formalise grammar, sibawayh, was not even an arab, he was persian. t.'
